I have an Amplify application configured and I am trying to test a AWS Lambda function locally using the command amplify mock function, an error occurs however stating that the module requests is not found as shown below.
> amplify mock function
? Select the function to mock MLFunction
? Provide the path to the event JSON object relative to C:\Users\warre\OneDrive\Documents\College\Msc\FinalYearProject\AWS\Amplify_Tutorial\amplify-app\amplify\backend\function\MLFunction src/event.json
Ensuring latest function changes are built...

Finished execution.
To install the requests package I used the following commands.
cd .\amplify\backend\function\MLFunction\
pipenv shell
pipenv install requests
The virtual environment I can see is under C:\Users\<USER>\.virtualenvs\MLFunction-flLToiwL\ and within the path C:\Users\<USER>\.virtualenvs\MLFunction-flLToiwL\Lib\site-packages the requests package is there.
The pipfile under .\amplify\backend\function\MLFunction\ also contains the following.
[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true
[dev-packages]
[packages]
src = {editable = true, path = "./src"}
requests = "*"
[requires]
python_version = "3.9"
When the function is deployed onto AWS it works fine, it is just local testing using amplify mock function which causes problems.
